The Use of Constant Volume Sampler and Dilution Tunnel to Compare the Total Particulates from a Range of Automotive Engines

The development of a simple CVS particulate test and its application to various engine types is shown to quantify a number of problem areas.

Research into the reduction of particulates in exhaust gases can be carried out more effectively by this technique than by the older optical methods.

These investigations however lag far behind those into the better known gaseous emissions.
